# This test isn't standalone for now. It's executed from the `.cci.jenkinsfile`.
# It expects to be running in cosa workdir where a single fresh build was made.

# Test that first build has been pruned; create a few builds for testing. Note
# these builds are cheap to make because we invalidate the image input data, but
# don't actually ask for a image rebuild since we use `ostree`.
# FIXME: Add env COSA_BUILD_DUMMY=true or something instead of using this subtle
# hack. Or better add `cosa build --shortcut=overrides` or so.
